presentationController(_:prepare:)

Provides an opportunity to configure the adaptive presentation controller after an adaptivity change.

Declaration

optional func presentationController(_ presentationController: UIPresentationController, prepare adaptivePresentationController: UIPresentationController)

Parameters

  • presentationController:

    The presentation controller that is managing the adaptivity change.

  • adaptivePresentationController:

    The adaptive presentation controller to prepare. Configure this presentation controller’s properties as necessary before it presents.

Discussion

The system calls this method during adaptation so the delegate can configure properties of the adaptive presentation controller before it presents.

For example, the system automatically adapts a view controller that presents as a popover in standard size classes to a sheet in compact size classes. You can implement this method to customize the sheet’s properties before it presents.
